Doubling up does solve the flux problem, but means a lot of
resistance - MOTs usually start with high Rs for their rating.
More transformers in parallel can compensate so size is then the
downside.
Normally, 10 or 15% reduction in volts is enough to bring the
magnetising current down, so rewinding one to work as a 'buck'
feeding 4 or 5 others is another option for the thrify types.

So if you take a MOT with a 120V primary and series it with an
identical MOT and plug it into 120V we have solved the flux
problem.... correct?
Now the issue is what is the resultant individual secondary
voltages, how are we going to connect those windings, and what
rectifier circuit do we want?
Having never bothered with a MOT I'll leave the final answers
to others but when something is free it begs a solution.
